track-section maybe varied at willfrorn straight parallelism' to any desired degree of cooperate with inclines E E on the shoes or skids G G, which lieparallel with the tracksection, and rollers D D, which are adapted to engage yokes or straps F F, which are also connected to the skids or shoes G G and overlie the inclines E E. `ZVhen the shoes or skids G G are no t resting on the ground, they hang on and are supported by rollers D D under the straps or yokes F F.

On one of the axles of `the wheels H (which sprocket-wheel J) is mounted a drum K, which justine; the turnbuckles the direction ofthe are propelled in the usual way from the carries two ropes L L', leading oii' in either direction and attached at their ends to the cross rods or ties 0 O of the tracks M M.

The traversing action of the machine isas follows: From tithe engine or other prime mover of the machine on the car the latter vis propelled along the tracks M M for several tive connection with the car-axles. The rope Lf assures no slipping of the wheels. Th.

tend to lift the shoes or skids G G from the ground, and thereby drag them along with the car. j The engine isthen reversed, and as the car starts backward the` rollers C C ride up the inclines E E, forcing the Shoes or skids against the ground and lifting the car and its trucks clear of the tracks M M. The rope L assumes the strain incidentto hoisting the car up the inclines E E after the car-wheels have left the tracks, and as the rope L is attached to 'the tra`ck-section and the' latter is 'relieved 1.35 rollers DD, working under the Straps F F,

of lthe weight of car the friction of the track against theground is inadequate to hold the rope. Therefore the track-sectionis slid forward to an advanced position. The engine is again reversed, the car lirst rolls down the` clines E E just far enough to clear the wheels of the invention.

VlThat'I claim is v l' l. Apparatus for traversingr or transporting Iexcavators or other heavy machinery, comprising a movable track-section upon which the machine is mounted, means for lifting the machine from the track-section. at intervals, and means for alternately advancing the tracksection and the lifting ni'eans as they are relieved of the weight of the machine.

2. Apparatus for traversing' or transporting excavators or other heavy machinery, comprising a movable track-section upon Whichthe machine is mounted, means movaloiy connected with the. machine for lifting the same from the track-section at intervals, and means for advancing the track-section when the latter is relieved of the weight of the machine.

3. Apparatus for traversing or transporting i excavators or other heavy machinery, comprising a movable track-section upon which the machine is mounted, means movably connected with the machine for lifting the same from the track-section at intervals, and power mechanism on the machine for advancing the movable track-section when the latter is relieved from the weight of the machine.

4. Apparatus for traversing or transporting excavators or other heavy machinery, comprising a movable track-section upon which the machine .aiilvances`= an auxiliary supportingsection 'for liftingihe machine from the main track, and means iol' successively advancing the respective sections they are relieved of the weight of the machine.

5. Apparatus for traversing or transporting excavators or other heavy machinery, comprising a movable track-section upon which the machine advances, an auxiliary supportingsection connected to the machine and having inclines for liftingthe machine from the main track-section and means for successively advancing the respective sections as they are relieved of the Weight of the machine.

6. Apparatus for traversing or transporting excavators or other heavy machinery, comprising a movable track-section upon which the machine advances, an anxiliary section having inclines thereon, brackets connecting the machine and the auxiliary section and coperating with the inclines to lift the machine from the main track-section, and means for successively advancing the respective sections as they are relieved of the weightof the'machine.

7. VApparatus for traversing or transporting excavators or other heavy machinery,comprising-a movable track-section upon which the machine advances, an auxiliary section comprising skids having incline-.s and supportingyolresthereon, brackets on the machine having rollers cooperating with the inciines and yokes to lift the machine and advance the skids respectively, and means operated hy power mechanism on the machine for advancing the main track-section as the .latter is reiieved of the weight of the oar.

8. .apparatus for traversing or transporting excavators or other heavy machinery,comprising a movable track-section upon which the machine advances, an auxiliary section comprising skids having inclines and supportingyolres thereon, brackets on the machine having rollers cooperating with the inclines and yokes to lift the machineand advance the skids respectively, a drum cn the axle of the machine, a cahle wound on the drum and connected at its ends to opposite points on the main track-section, and power mechanism on the machine for driving said axle.

9. In mechanism for traversing or transporting excavators or other heavy machinery, a movable track-section, and means connected therewith for varying the direction of the advance of said track-section.

l0. lin mechanism for traversing or transporting excavators or other heavy machinery, a. movable track-section, and adjustable memhers in the rails -of said track-section for varying the direction of advance of the respective rails from straight parallelism to any desired degree of curvature.

11. In mechanism for traversing .or transporting excavators or other heavy machinery,l

a movable track-section, and turnhuc'kles intei-posed between the rails of said track-sec.- tion for varying the direction of-the latter.
